My wife was a teacher before we had kids. She left the profession for exactly the reasons you mention. She liked teaching children. She hated dealing with discipline and especially with needy parents who would not trust her when she said that their child wasn't any better than any other student. She hated the fact that they wouldn't let her teach advanced concepts to advanced kids, and that they got rid of tracking and classroom aides. When her job became more overhead than actually teaching, that's when she called it quits. Now she volunteers most of the day at school trying to help the teachers in any way she can to make their jobs easier.
